AWS recently announced that Amazon ECS now supports a state for container instances that can be used to drain a container instance in preparation for maintenance or cluster scale down. AWS reports that the draining state prevents new tasks from being started on the container instance and notifies the service scheduler to move tasks that are running on the instance to other instances in the cluster. This is great news that we expect to save a lot of time and scripting when it comes to updating or removing containers from a cluster.
Amazon announced its Elastic Container Service (ECS) at re:Invent 2014 using Pristine as a case study. Given Flux7’s Amazon expertise, it’s likely no surprise to frequent readers of this blog that Pristine is a Flux7 customer who we have been working with for some time now.
Those migrating to the cloud are often confused by performance on AWS. With so many metrics, they’re not sure which ones pertain to their application needs. The biggest questions seem to center on network performance characterized as “low,” “medium,” and “high,” which is why we’ve focused on network performance for this series on AWS performance benchmarking. To measure network performance we chose the industry-standard benchmark Iperf and used i2.8xlarge instances.
